PROBLEM TO BE SOLVED: To realize a structure capable of restraining an abrasion quantity of a friction material 28, by stabilizing a friction coefficient between both side surfaces and a mating surface of the friction material 28. SOLUTION: A lubricant such as grease is interposed in a frictionally engaging part between both side surfaces and the mating surface of the friction material 28. Together with this, holding spaces 29a and 29b for holding the lubricant are respectively arranged on both sides in the radial direction of these respective frictionally engaging parts. The problem is solved by adopting this constitution. COPYRIGHT: (C)2006,JPO&NCIPI
